What's Going on With the Volcano?

 
The eruption of Kīlauea volcano continues at two locations. In the park, the vent within Halema'uma'u Crater is easily viewed from the overlook at the Jaggar Museum. The second location is the Pu'u 'Ō'ō vent located 10 miles (16km) east of the summit, on the remote east rift zone of Kīlauea. This area is not accessible to the public. There is no lava flowing into or towards the ocean.

Fumes and glow from the lava lake within the vent at the summit of Kīlauea may be seen from the Jaggar Museum overlook and other vantage points along Crater Rim Drive.

During the day a robust plume of volcanic gas is a constant and dramatic reminder of the molten rock churning in a lava lake within the crater. After sunset, Halema'uma'u continues to thrill visitors and park staff with a vivid glow that illuminates the clouds and plume (weather permitting).

Park rangers are on duty at the Jaggar Museum to assist the many visitors drawn to the site which has been erupting within the crater since March 2008.

HOT LINES for Eruption Information

The June 27th lava flows from Pu'u 'Ō'ō are outside of Hawaii Volcanoes National Park's eastern boundary. The flows are inaccessible by foot or by car and the area is closed to the public.

Activity Summary: Kīlauea Volcano continues to erupt at its summit and within its East Rift Zone. A lava flow front consisting of two fingers remains active and advanced ~150 m (~165 yds) since yesterday according to Civil Defense. The leading edge of this front is approximately 1.3 km (0.8 miles) above the intersection of Pāhoa Village Road and Highway 130, near the Pāhoa Marketplace. A summit deflation event began last evening. No significant tilt has been observed at Puʻu ʻŌʻō since yesterday's report.

June 27th Lava Flow Observations: HVO, along with Civil Defense, is monitoring a flow front that branches off the west edge of the flow field below the crack system. Civil Defense reported this morning that the leading edge of the flow was about 1.3 km (0.8 miles) upslope from the intersection of Pāhoa Village Road and Highway 130, near the Pāhoa Marketplace. As of this morning, Civil Defense photos also show that the flow front consists of two closely spaced fingers, both headed towards the intersection of Pāhoa Village Road and Highway 130, in the vicinity of the Pāhoa Marketplace. In addition to this active flow front, breakouts from the lava tube on December 5, about 2.6 km (1.6 mi) from Puʻu ʻŌʻō remain active. Yesterday, HVO staff installed two new time lapse web cameras in the vicinity of Pāhoa Marketplace. One of these cameras is trained on the market itself, and the other is directed up slope. Images from these cameras are available on the HVO website (http://hvo.wr.usgs.gov/cams/) under the heading Webcams/ East Rift Zone.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of Kīlauea's active East Rift Zone lava flow. The area of the flow early yesterday morning (December 15) is shown in pink, while advancement of the flow as mapped on December 16 at 11:15 AM is shown in red.

The active tip of the flow was about 1.5 km (~0.9 miles) from the upslope edge of the Pahoa Marketplace along the path of steepest descent that the flow is currently following. The flow width varies from about 30 to 230 m (33 to 250 yd), and the current flow front is near this maximum width. Tick marks have been placed along the steepest-descent path at an interval of 0.4 miles, measured from Pahoa Marketplace.

The blue lines show steepest-descent paths calculated from a 1983 digital elevation model (DEM; for calculation details, see http://pubs.usgs.gov/of/2007/1264/). Steepest-descent path analysis is based on the assumption that the DEM perfectly represents the earth's surface. DEMs, however, are not perfect, so the blue lines on this map can be used to infer only approximate flow paths. All older Puʻu ʻŌʻō lava flows (1983–2014) are shown in gray;the yellow line marks the active lava tube.

This small-scale map shows Kīlauea's active East Rift Zone lava flow in relation to lower Puna. The area of the flow on December 9 at 2:30 PM is shown in pink, while widening and advancement of the flow as mapped on December 16 at 11:15 AM is shown in red.

A relatively narrow lobe of lava continues to advance downslope toward the Pahoa Marketplace. The tip of the flow was at 19.498695 , -154.969467 (Decimal Degrees ) at an elevation of 220 m (720 ft). This is about 1.5 km (0.9 miles) from the upslope edge of the Pahoa Marketplace, as measured along the path of steepest descent that the flow has been following. Several other breakouts were active farther upslope along the narrow lobe, as well as within the crack system and on the upper part of the flow field northeast of Puʻu ʻŌʻō.

This large-scale map shows the distal part of Kīlauea's active East Rift Zone lava flow in relation to nearby Puna communities. The area of the flow on December 9 at 2:30 PM is shown in pink, while widening and advancement of the flow as mapped on December 16 at 11:15 AM is shown in red.

Most change on the flow field is due to advancement of the relatively narrow lobe of lava continues to advance downslope toward the Pahoa Marketplace. The tip of the flow at the time of mapping was about 1.5 km (0.9 miles) from the upslope edge of the Pahoa Marketplace, as measured along the path of steepest descent that the flow has been following. This particular flow branch, which started from the crack system near the True/Mid-Pacific well site on November 19 (27 days ago), is now 8.0 km (5.0 miles) long. This equates to an average advance rate of 300 m/day (330 yd/day) over that period.
